The three labour groups: Nigeria Labour Congress (NLC), Trade Union Congress (TUC) and United Labour Congress (ULC) had directed workers to proceed on a seven-day warning strike effective from Thursday.
The labour unions had issued the directive after the expiration of a 14-day ultimatum given to the government to announce and implement the new national minimum wage as promised.
The federal and state secretariats in Ibadan were deserted as workers obeyed the sit-at-home order.
The entry gates of the secretariats were locked.
